ANTIFRICTION-"BEARING.

Specification of Letters Patent.

Patented May 1, 1906.

Application filed October 20, 1904. Serial No. 229,292.

To all whom it may concern:

Be it known that 1, WILLIAM THORNTON, a resident of Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Antifriction-Bearin s; and I do hereby declare the following to e afull, clear,

and exact description of the invention, such. as will enable others skilled in the art toments applied to the gear of a Wash1ng-ma' chine; and Fig. 2 is a view in vertical section of the gear and bearing.

1 represents a frame to ing-machine and providing a thrust-bearing for a contracted trunnion 2 at the upper end of a vertical dasher rod or shaft 3.

4 represents a bearing-ring adapted to rest in an opening in the washing-machine top, (not shown,) and 5 is a gear secured on the shaft or rod 3 and to WlllCh motion is transmitted in any desired manner to turn or reciprocate the rod or shaft 3. The gear 5 has a cylindrical depending portion 6 projecting into ring 4, which latter 1s made with an annular recess 7 to receive a series of rollers 8, located between the cylindrical portion 6 of the gear and the vertical wall of recess? and the lower ends of these rollers 8,which rest on the horizontal or bottom wall of recess 7, are contracted 'to reduce friction. The lower end of the cylindrical portion 5 of the gear is made with a curved oove or runway 9, and the ring 4 has a simi ar runway "10, between which a series of balls 11 is mounted.

By constructing my improvements as above explained it will be seen that the balls 11 sustain any downward strain, and rollers 8 be fixed to a washsustain the lateral strain, relievin the arts of frictional contact both vertically an laterally and resulting in an extremely 'easyrunning bearing in which friction is reduced to a minimum.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is r 1. An antifriction-bearin comprising a fixed member having an annu ar recess therein, a rotary member provided with a cylindrical portion mounted in said recess, elonated rollers in said recess between the memers having contracted ends seated upon the base of the recess in the fixed member, and means for sustaining the rotary member free of the other ends ofthe elongated rollers.

2. An antifriction bearin comprising a fixed member having an annu ar recess and a roove below said recess, a rotary member aving a cylindrical ortion mounted in said recess and rovided with a groove at its lower end, e ongated rollers in the recess surrounding the cylinder and balls mounted in the grooves in the fixed member and the cylindrical portion of the rotary member and sustaining the rotary member free of the upper ends of the elongated rollers.

3. An antifriction-bearing comprisin a fixed ring having an annular recess and a groove below said recess, a rotary member having a cylindrical portion disposed within said fixed member and having a oove at its lower end, elongated rollers in said recess between the cylindrical portion of the rotary ,member and the verticalwall of the recess,

said rollers having contracted ends sup orted upon the bottom of the recess, an mounted to run in the grooves in the cylindrical portion of the rotary member and the ringhand sustainin the rotary member free f t e elon ated r0 lers.

' 4. In a evice of the character described, the combination with a frame, a vertical shaft having a bearing at one end in the frame, a rotary member secured on the shaft, said rotary member having a cylindrical depending portion provided at its lower end with a groove,'a fixed ring having an annular recess, and also having a groove below the balls v recess, elon ated rollers mounted in said respecification in the presence of two subscrib l ing Witnesses.

cess, and be ls mounted in the grooves in the fixed ring and the cylindrical portion of the fixed member and sustaining the rotary 5 member free of the upper ends of the elongated rollers.

In testimony whereof I have signed this -WILLIAM THORNTON. l Witnesses:
